          align
              Sets the horizontal alignment of the text content
              within hover label box. Has an effect only if the hover
              label text spans more two or more lines
          bgcolor
              Sets the background color of all hover labels on graph
          bordercolor
              Sets the border color of all hover labels on graph.
          font
              Sets the default hover label font used by all traces on
              the graph.
          grouptitlefont
              Sets the font for group titles in hover (unified
              modes). Defaults to `hoverlabel.font`.
          namelength
              Sets the default length (in number of characters) of
              the trace name in the hover labels for all traces. -1
              shows the whole name regardless of length. 0-3 shows
              the first 0-3 characters, and an integer >3 will show
              the whole name if it is less than that many characters,
              but if it is longer, will truncate to `namelength - 3`
              characters and add an ellipsis.
